I have this login.xhtml JSF page:
<?xml version="1.0"?>
<jsp:root version="2.0"
xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<jsp:directive.page contentType="text/html"/>
<f:view>
<h:inputText value="#{userBean.id}"/>
</f:view>
</jsp:root>
Output HTML contains properly rendered <input> tag, but <jsp:*> are left untouched. Seems that JSF just didn't understand them. Why?
The JSP tags you use don't generate any HTML.
The contentType directive affects header, not HTML.
You need to activate JSF, a common way is to point the browser to login.jsf or faces/login.xhtml. If you don't then the file is serves unparsed to the browser
Your're using JSF 2.0 and the file has a *.xhtml extension. You're actually using Facelets as view technology, not JSP. Facelets is the successor of JSP. You cannot mix Facelets with JSP tags. Get rid of all <jsp:> tags, they are worthless and ain't ever going to work in a Facelets page. The JSP tags are only parsed when you name the file *.jsp which will be picked up by servletcontainer's builtin JspServlet. But since you're using JSF 2.0 with Facelets, you already have the FacesServlet for the job. Forget JSP :)
Here's how your XHTML file should look like:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>Title</title>
</h:head>
<h:body>
<h:inputText value="#{userBean.id}"/>
</h:body>
</html>
Note that you'd like to put that input component in a <h:form>, but I bet that it'll be just a test example.
Also note that <!DOCTYPE html> is perfectly legit here. You don't need the XHTML doctype. Facelets will take care about setting the right text/html content type, UTF-8 character encoding and so on.
